WebThe radar equation shows how the received power is governed by multiple variables. As expected, the power drops very rapidly with the distance which is governed by the term 1/R 4, where R is the distance between the radar and the target. The power is also governed determined by the gain of the transmit and the receive antennas G t x and G r x .This …
